Ya, that's a good video. Audio straight from the desk. Here it is in the room:

You can hear the clarity going when the bass line kicks in, just like I described earlier.
You can also hear how shit your camera's mic is too when its exposed to high decibel levels.
Can you get any special mics that would be good for recording in live venues,
i.e being able to take more dBs without distortion?
